Option to suppress discount message

[bkonia]

For each product in the cart and on the checkout page, the plugin displays a message like:

(Incl. 10% discount)

Could you add an option in the settings to suppress this message, or perhaps add a box where the user can enter his own template for the message, or leave it blank to not display anything.
